An electronic textbook includes nodes containing items of educational content, and a plurality of paths through the nodes. Each path represents a different organization of the nodes in the electronic textbook. The paths are tailored to the educational needs of the users of the electronic textbook. As a user traverses the nodes of the electronic textbook, the user creates a personalized path. The user can add comments to the nodes and connections of this path. These paths and associated comments are made available to other users of the electronic textbook. |
